5 Claims.

My invention relates to hair curling appliances and in one form of its use is particularly of value in connection with what is called permanent waving of hair.

' My invention is designed to provide instrumentalities by virtue of which a more thorough and uniform curling of the hair is made possible. By the use of these instrumentalities it is possible to reduce the length of the uncurled hair adjacent to the scalp and it is also possible to provide a more uniform curl, that is, one in which the difference between the length of each wave is reduced, that is my improved device separates the strands of hair to a greater degree than has heretofore been possible so that each strand when Wound upon a mandrel does not have as large an outer diameter as is customary in the present devices. Thus the wave in the outer layers of the hair more nearly approximates the length of wave of the inner layers.

It is another object of my invention to arrange a device of this nature which can be used with the standard heating appliances that are mounted above the curling elements after the curling elements are in place, that is, my improved device although providing for two strands of hair in connection with each device, nevertheless is of such a size that it would fit the standard heating unit as used in connection with other devices having but a single mandrel or curling element.

A further advantage which accrues due to the use of my invention is that it takes less time for the steam or other heating means to penetrate the wound strand, and if steam is used, it more readily penetrates to the interior because of the smaller diameter of the curled strand.

In accordance with my invention I provide an instrumentality of this type in which two strands of hair may be accommodated and I so arrange this instrumentality so that it may be opened to receive the hair, and locked to clamp the same in position even though the instrumentality is placed immediately adjacent another like instrumentality in which-other strands of hair have already been clamped.

I will describe one form which my invention may take more in detail by referring to the accompanying drawing in which Fig. 1 is a top view of such an instrumentality;

Fig. 2 is a partial sectional view on line 2-2 of Fig. 1;

Fig. 3 is a sectional view on line 3-3 of Fig. 2;

Fig. 4 is an open view of the clamping device;

Fig. 5 is a view showing the arrangement of various instrumentalities of like nature;

Fig. 6 is a perspective view of the underlying pad; and

Fig. '7 is a sectional view on line I of the extremity of one of the mandrels.

Referring more particularly to Fig. 4, I show 5 there my improved clamping device which consists of a back plate III to which three clamping elements I I, I2 and I3 are pivotally mounted, although the central element is preferably stationarily arranged as shown. The clamping elements as shown more clearly in Fig. 3 comprise central metallic portions I4 surrounded by rubber envelopes I5. The back plate I0 is preferably an L-shaped element having upwardly projecting fingers I6, I! and IS, the slots between the fingers furnishing a guide for the extremities of mandrels I9. The right hand extremity of the clamping element I3 (Fig. 4) is provided with a locking device pivotally mounted thereon which consists of an upper front plate and a lower front plate 20 2|. The upper front plate 20 is likewise provided with three fingers, respectively the fingers 22, 23 and 24 which serve a purpose similar to the fingers I6, I1 and I8 in that they accommodate the opposite extremities of the mandrels 25 from that accommodated by the fingers I6, I! and I8.

The right hand extremity 25 of the clamping element I2 is flat so that it may enter between the two plates 20 and H and the same is true of the right hand extremity 26 of the clamping element I I.

Between the upper and lower plates 20 and 2| of the locking device there is mounted a lever 21 having an eccentric 28. Thus when the three clamping elements II, I2 and I3 are pressed together as shown in Fig. 1, then the lever 27 may be swung in a contra-clockwise direction (Fig. 4) and the eccentric 28 finds its position in the round side portion 27' of the element 26 and locks the three clamping elements together as shown more clearly in Fig. 1.

It is of course to be understood that two strands of hair are first to be inserted between the clamping elements, respectively, these two strands being shown more clearly at 29 and 30 in Fig. 3.

My improved device, as before stated, is no wider than those now in use so that it can be accommodated within the individual heating element used on standard machines. The scale that is used in the drawing is somewhat larger than the actual device. In the particular form of the device which is used as a basis for the drawing the width of the device roughly is a little better than one inch.

Before the two strands of hair are introduced between the clamping elements ll, l2 and I3, they are drawn through a pad 3|, which pad preferably consists of a felt portion' 32 and a rubber or rubberized portion 33, this pad having two slots 34 and 35 through which the strands are initially drawn and the pad placed against the scalp. These pads are separate from the clamping device or element.

In use therefore, the two strands of hair are drawn through slots 34 and 35 and then inserted between the clamping elements ll, l2 and I3,

whereupon the clamping elements are locked to gether. The free extremities of the two strands are then wound upon two mandrels I9, 19 and as the hair is being wound upon these mandrels,-

the mandrels approach closer to the clamping element until finally their opposite extremities pass into the slots between the fingers l6, l1, I8,..

22, 23 and 24, respectively. These mandrels are each provided with a finger 36 to thoroughly hold both'being round, permit continuous rotation of the mandrel. until it approaches the position shown in Fig. 3, whereupon the mandrel is pushed to the right (Fig. 1) so that the squared portion 38 enters into the slot between the fingers to be there held while the mandrel is further rotated in order to tighten the strand upon the mandrel. The locking instrumentalities shown in connection with the mandrel prevent reverse rotation of the mandrel after this final tightening process.

In order to obtain a still tighter adjustment of the mandrel, it is provided with a plurality of holes 4! into which a small rod may be inserted for that purpose, thus to obtain a greater leverage. To release the mandrel it is pushed to the left to release the square shaft portion from between the fingers.

It will be seen that because the three clamping elements ll, l2 and I3 are clamped by means of r a lever operated from one side thereof, that a second clamping device may be mounted adjacent to the onealready in position so that the two may closely adjoin, all as shown more clearly in Fig. 5.

I prefer to have the pads 3| overlap as shown in Fig. 5 so as to be doubly safe in guarding the scalp from the heat that is being applied from the heating elements. It must be understood, of course, that the drawing illustrating this overlapping arrangement in Fig. 5 is not exactly correct in that the tilting of the elements is not so pronounced as shown in Fig. 5 but the pronounced I From what has been described it will be seen that if a device of this nature is used in which the total amount of hair which is to be curled and which is drawn from beneath the device is divided into two strands, that the length of. the uncurled hair adjacent to the scalp is considerably less than if the hair were drawn through such a device in one strand only. Two strands likewise make it possible to have a wound strand of less-diameter than if all of the hair is wound in a single strand. I find that by the use of my improved devices I can utilize more on a scalp than with the older type of devices.

From) what has been thus described, it is thoughtthat the nature of my invention will be readily. clear .to those skilled in the art. Having, however, thus described one form which my invention may. take, what I claim as new and desire to secure by Letters Patent is:

l. A device for use in the permanent waving of hair and adapted to clamp strands of hair therein comprising three separable clamping ele ments mounted together, and means operable at one side thereof for locking said clamping elehair and adapted to clamp strands of hair therein comprising three separable clamping elements mounted together, means operable at one side thereof for locking said clamping elements to gether, and an insulating pad having slots through which said strands of hair are passed.

4. A device for use in the permanent waving of hair and adapted to clamp strands of hair therein comprising three separable clamping elements, an end plate to which said elements are 'mounted, fingers extending upwardly from said end plate, two of said elements having swinging engagement with said end plate, and a unitary locking device carried by the opposite extremity of one of said elements for locking said elements together.

5. A device for use in the permanent waving of hair and adapted to clamp strands of hair therein comprising three separable clamping elements, an end plate to which said elements are mounted, two of said elements having swinging engagement with said end plate, a unitary locking device carried by the opposite extremity of one of said elements for locking said elements together, and fingers projecting upwardly from said locking device for accommodating mandrel extremities therebetween.
